Abstract
Active Antenna Unit (AAU) is the main part of the 5G base station that has a great size with a high density of chipsets and be operated with significantly high temperature. This study addresses an effect of geometric parameters of heat sink on thermal dissipation for AAU. The heat sink is investigated in two designs of fin such as in-line and V-shaped arrangement fins heat sinks. This research is implemented in two stages for making comparisons of these types. Firstly, we validated the simulation results from the computational fluid dynamics (CFD) method with an in-lab experimental model measured by an infrared thermometer. In the next step, two larger prototypes of heat sink are proposed to consider the actual impacts of V-shaped heatsinks on thermal dissipation. The simulation and experimental results demonstrated that in general, the heat sink with V-shaped fin has the better performance on thermal dissipation in comparison to conventional models such as in-line arrangement fin heat sinks. It is worth noting that the V-shaped heat sink advantage is more noticeable in the bigger models.
